Firstgear Heated Jacket Liner Firstgear's no one left behind policy ensures that riders of any model motorcycle can take advantage of the warming effects of heated apparel by choosing between either the 65- or 90-watt versions. Good for low-amperage bikes or passengers not requiring as much heat as the rider, the 65-watt units minimizes the draw on the bike's charging system. The 65 watt version is black, while the 90 watt version is grey. Efficient warming is dependent upon close proximity to the body. Firstgear reduced the amount of sizes while ensuring a good fit by incorporating stretch panels into the liner's design. The long-sleeve liner cocoons its wearer in warmth by incorporating heating elements across the upper and lower back, down the sleeves, around the neck and, to combat the effects of windchill, the liner concentrates heat in the front of the jacket.

I had always thought that layering was the best defense against cold. I was wrong. With this heated jacket liner I have ridden with just a t-shirt, the liner and my riding/protective jacket in 20 degree F weather. No more bulk! In the afternoon when things warm up, just turn down the temp on the optional controller and stay comfortable. I can see wearing this on cooler summer mornings and just turning it off when it is not needed any longer. No more pulling off the road and taking everything off so you can get to the middle layer. I have the 90W version because My BMW can handle the draw.
